Comunnicaton error via HTTPS

Hello,
I have Flash AIR application, that communicates with server via HTTPS protocol. On MAC I install requested certificate and it works fine, but unfortunently on Windows 7 and XP I have this error:

“[IOErrorEvent type=“ioError” bubbles=false cancelable=false eventPhase=2 text=“Error #2032” errorID=2032]”

I aasume its something wrong with system configuration, but anyone know how to fix this?
